Which of the following is a thermosetting polymer?
- Buna-N
- PVC
- Bakelite
- Nylon 6
The Correct Option is C
Solution and Explanation
Bakelite is a thermosetting polymer, meaning it undergoes irreversible chemical reactions during its curing process to form a hard, infusible, and insoluble material. Once molded and cured, Bakelite cannot be softened or reshaped by heating, making it suitable for applications requiring high heat and chemical resistance, such as electrical insulators and durable handles for cookware.
So, the correct option is (C): Bakelite.

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
